a rumor that was told initially to three people is spreading at a rate of 5% each week. the following function represents the weekly spread of the rumor: f(x) = 3(1.05)x. rewrite the function to show how quickly the rumor spreads each day and calculate this rate as a percentage.
a) f(x) = 3(1.007)7x; spreads at a rate of approximately 0.7% daily
b) f(x) = 3(1.05)7x; spreads at a rate of approximately 0.5% daily
c) f(x) = 3(0.15)x; spreads at a rate of approximately 0.15% daily
d) f(x) = 3(1.007)x; spreads at a rate of approximately 0.07% daily

I think D would make the most sense here

Step-by-step explanation:

If it's spreading 5% each week, that means it has to be a smaller amount each day... like it couldn't spread 15% in a day because that's already over 5% for the whole week

The Answer is DEFINITELY NOT D, its C

Step-by-step explanation:

I did the Flvs test a second ago and picked D, guess what I got the question wrong, its C

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
